Underlying Assumptions and One-Way ANOVAs

Many researchers who use a one-way ANOVA seem to pay little or no attention to the assumptions that underlie the F-test comparison of their sample means. Consequently, I encourage you to feel better about research reports that (1) contain discussions of the assumptions, (2) present results of tests that were conducted to check on the testable assumptions, (3) explain what efforts were made to get the data in line with the assumptions, and/or (4) point out that an alternative test having fewer assumptions than a regular one-way ANOVA F-test was used. Conversely, I encourage you to lower your evaluation of research reports that do none of these things.
